Tamron SP AF 35mm F/1.8 DI VC USD Lens - Canon Mount
100% Genuine Australian Stock
2-Year Tamron Australia Warranty
A standard 35mm slightly skewed to a wide-angle lens with built-in VC provides an MOD (Minimum Object Distance) of 0.2m. Tamron SP AF 35mm F/1.8 DI VC USD Lens achieves superb imaging performance at full aperture with well-balanced depictive capability. State-of-the-art design and engineering technologies backed by manufacturing know-how culminate in this fine lens.
High performance at f/1.8 full aperture
The open aperture is set to f/1.8 with optimised critical properties at a higher level: superb optical performance coupled with a VC system, a shorter MOD, and a well-balanced form factor. Rigorous simulation processes performed throughout the design phase are materialised in distinguished resolving power and beautifully tuned background blur, a prominent feature to a fast-aperture, full-frame compliant optic.
VC (Vibration Compensation) integration sets itself apart
VC really comes into its own when used on high-resolving professional DSLRs which pick up even subtle camera shake. On fast-aperture lenses, VC dramatically extends the ability to shoot handheld under dim light conditions by eliminating camera shake at slower shutter speeds.
USD (Ultrasonic Drive)
The USD actuator converts ultrasonic waves into rotational motion that delivers autofocus with responsiveness, accuracy, and speed without so much as a whisper. The photographer can easily use manual focus at any point while the AF system is operating without having to fumble for a switch.
Get closer than ever before
New MOD specs let photographers shoot at close range, opening a new world of creative opportunities for composition while maintaining image quality. With an MOD of 0.2m, the SP 35mm offers best-in-class close focusing**. A floating system design feature seamlessly optimises image quality by shifting elements relative to the focus group in close shooting situations. This lens uniquely offers shooting characteristics like a wide-angle macro lens
Far superior image quality – while reducing lens size and weight
Tamron SP AF 35 mm/F1.8 DI VC USD uses several hybrid aspherical lens elements in its lenses bearing the Aspherical designation. The benefits are two-fold: first, in SP lenses of fixed focal length, molded glass aspherical elements deliver planarity in field curvature. These elements ensure superb focusing uniformity over the entire field by compensating for spherical and comatic aberrations. Second, as one hybrid aspherical lens element can take the place of multiple elements without compromising performance, they allow the lens to be much more compact.
Sharpens edges by reducing 'colour fringing'
Chromatic aberration occurs when a lens element refracts different wavelengths of a ray of light - its rainbow colours - at very slightly different angles. This results in the 'colour fringing' that reduces the sharpness of an image. LD elements are made from special glass materials with extremely low dispersion indices (i.e. the refraction of a ray of light into rainbow colours is extremely narrow). Thus they effectively compensate for chromatic aberration at the centre of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (toward the edges of the field) that often occurs at short (wideangle) focal lengths. Although costly, LD glass materials result in clear, vivid image quality.
Dispersive properties even lower than LD elements
Extra Low Dispersion Tamron SP AF 35mm F/1.8 DI VC USD Lens elements are made from a special high-grade glass that has dispersive properties (i.e. where refraction causes the dispersion of white light into spectral hues) even lower than standard LD lenses, in fact being similar to those of fluorite. In combination with LD elements, these make for an optimal optical design that delivers superb resolution with advanced correction of axial chromatic and magnification aberrations – major inhibitors of image quality. The result is a lens that delivers sharp contrast and better descriptive performance throughout the entire zoom range.
Advanced lens coating produces even sharper, crisper images
This new coating technique developed by Tamron deploys a nano-structured* layer with dimensions smaller than the wavelengths of visible rays of light. Called eBAND (extended Bandwidth & ANgular-Dependency), its ultra-low refractive index, combined with the sophisticated multiple-layer coatings underneath, yields significant anti-reflection properties, absolutely minimising flare and ghosting to deliver sharp, crisp images.
Cleaner, crisper images without flare or ghosting
BBAR coating provides crystal-clear images by suppressing element surface reflections that lead to ghosting and flare.
Developed for industrial optics, fluorine coating offers long-lasting oil and water resistance to the lens. Moisture and smudges wipe away, making it easy to keep your lens clean.
Optimal relative illumination
The two new SP lenses deliver exceptionally uniform illumination levels across the image field to avoid non-linear pattern or fall-off toward corners.
9 diaphragm blades for superb blur quality
The number of diaphragm blades affects the "shape" of the blur in out-of-focus areas of the image. This is more important in portraiture, where the aperture setting is often wide open, and macro photography, where the high magnification results in blurred background and foreground even at narrow apertures. When backgrounds are soft and blurred, not only is the effect very pleasing and "photographic", but it also serves to isolate the subject from a distracting background, providing a professional-looking image. A high number of blades provides a rounder shape to the aperture, which in turn makes the shape of the blur more circular and much more natural.
Performance takes priority for superb image quality
This line of ultra-high-performance lenses is designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. The foremost priority is achieving superior performance parameters – high design standards take priority over cost constraints. As a result, Tamron SP AF 35mm F/1.8 DI VC USD Lens features innovative designs that have established an enviable reputation for excellence amongst demanding photographers. Constructed to prevent moisture from entering the internal mechanisms of the lens, the SP line is sealed to allow photographers to shoot outdoors in adverse conditions.
'Travelling waves' generate a fast, smooth AF movement
This extremely quiet motor is ideal for photography of events, weddings, theatre or musical performances, as well as crucial moments on the golf course – any situation where autofocus noise is obtrusive. Major improvements in autofocus response and tracking ability over standard DC motors make for instantaneous focusing and spontaneous shooting of rapidly moving subjects.
